They combine advantages of electronic controllers with digital circuit “intelligence”. A possibility to program temperature in 24h and a week cycle. A possibility to read out on a LCD such data as: a room real temperature, previously programmed comfort and economic temperatures, a heating system operating time, a program number and its graphical image. Selected models have an adaptation function: the temperature controller “calculates” itself the heating switching off moment to reach a desired temperature at a programmed time. Load up to 3600 W. They can be surface or flush mounted.

* adaptative system (proportional-integral) adjusting the deviation to the set temperature depending on the duration of the temperature’s increase or decrease. Due to this feature the controller’s operational characteristics is self-adjusted to ambient conditions, in real time.
